Indian extremist party Bajrang Dal’s worker attacked Pakistan International Airline’s (PIA) office in Delhi, local media say.
The witnesses said some armed culprits barged into the PIA town office, ransacked equipment in the building and maltreated the office staff.
The same office had received threats some days ago, however, security at the facility was not beefed up despite repeated attempts.
The culprits chanted slogans against Pakistan and the Pakistani government.
There were no reports of any casualties, but the glass windows of the office were said to have been shattered and computers and other equipment damaged in the attack.
